DRAW-BAR-SLACK ADJUSTABLE SAFETY APPLIANCE.

eanna.

To all whom it may concern.-

Be it known that I, GEORGE SELLS, a citizen of the United States, residing at East Las Vegas, in the county of San Miguel and State of New Mexico, have invented certain new and useful Improvements in Draw-Bar- Slack Adjustable Safety Appliances, of which the following is a specification.

My invention relates-to draw bar slack adjusting safety appliances and more particularly to a bufling device used in connection with the same as set forth for example, in my Patent numbered 1,062,123 issued May 20, 1913.

The primary object of my invention is the provision of an improved buffing device in.-

-cluding intermediate casting or insert for allowing lateral movement of the buffer block and chafing iron and simultaneously providing a buffing device in which the parts at all times contact with each other, thus, obviating undue wear on the block and the lI'OIl.

Another object of my invention is to provide an improved chafing iron having means arranged therein for receiving the intermediate casting or insert.

A further object of my invention is to pro vide an improved means on the intermediate casting for guiding the same when engaged upon the chafing iron.-

A still further object of my invention is the provision of a device that is simple in construction, efficient in operation, and one that can be manufactured and placed upon the market at a minimum cost.

Other objects as well as the nature, characteristic features and scope of my invention will be clear from the following description taken in connection with the accompanying drawings.

In the drawings:' Figure 1, is a view in elevation of an embodiment of my invention. F ig. 2, is a perspective view of my improved chafing iron. Fig. 3, is a perspective view of my improved intermediate casting or insert. Y

Referring more particularly to the drawings in which similar reference numerals designate like or corresponding parts, I prothe main part of the car by means of bolts 2, and acting within the casing are wedges 3, the outer ends 4, thereof, being reduced and provided with openings 5, for the reception Specification of Letters Patent.

of the pins 6, employed for holding the ends of a connecting bar 7, thereto. Each bar is arranged to slide within a journal member 8, that is rigidly secured to a beam 9, carried by a car, the outer ends of the bars having washers 10, mounted thereon, and spring 11, disposed thereabout between the washers. Nuts 12, are in screw-threaded engagement with the outer ends of the bars, for the purpose of holding the springs 11, thereon, and for regulating the resilient action of the same.

Slidably mounted within the casing 5, is the neck 12, of a buffer block 13, the latter being provided with a slot 14, so that the wedges 3, can suitably act therein.

Rigidly mounted on the beam 15, carried by the adjacent car or engine, (not shown), by means of bolts 16, is the neck 17, of my improved chafing iron, 18, the outer bearing surface 19, of the same being enlarged, and convex in contour and symmetrical with respect to the convex bearing surface of the block 13, for a purpose to be hereinafter described.

Removably disposed between the convex bearing surface 19, of the chafing iron 18, and the convex surface 20, of the block 13, and automatically disengageable upon the separation of two adjacent cars is my improved intermediate casting 21, the latter having a width substantially the same as the width of the block and provided with com- 18, and the block 13 and adapted for movable engagement therewith. The casting is further provided on one of the bearing surfaces thereof with the laterally-extending tapering and rounded neck 24, for removable engagement with the inwardly-extending tapering and rounded recess 25, of a depth substantially the same as the length of the neck 24, formed in the bearing surface of the chafing iron 18, the width of the outer edge of the recess being greater than the width of the inner edge of the neck 24, to permit of the lateral movement of the parts when rounding a curve. For the purpose of holding the intermediate casting 1n operable position in guiding the same during movement, I have formed on the outer and lower edges of the same above and below the neck 24, laterally extending semicircular flanges 26, for engagement With the upper and lower surfaces of the chafing iron, as clearly shown in Fig. 1.

It is now apparent that'I have provided a casting that is removably disposed and pivoting against either the block or iron and retained in position by the proximate relation of the said block and iron.

By the arrangement of the casting with the block and iron, it can be easily seen that I have provided a bufiing device that ohviates undue wear on the latter elements, because of the fact that the parts are at all times contacting with each other. It must be noted that I do not entirely limit myself to the specific arrangement of the slack-adjusting appliance, the latter being merely illustrated and described to aid in thoroughly understanding the important features of my invention.

. It will be obvious to those skilled in the art to which this invention relates that modifications may be made in detail without departing from the spirit or scope of my invention.

I-laving thus fully described my invention what I claim as new and desire to secure by Letters Patent is:

1. A buffer for railroad cars including a buffer block carried by one car, a chafing iron carried by an adjacentcar, a casting removably disposed between said block and said iron and having a freely disengageable and pivoted bearing against said iron, and said casting being automatically disengageable from the block upon the separation of the car yet retained in a supported position with respect to the iron.

2. A buffer for railroad cars including a buffer block carried by one car, a chafing iron carried by an adjacent 'ar provided with a flared recess, a cast-ing disposed between the block and iron, and a neck extending from the casting and pivoting against the inner end of the recess.

3. A buffer for railroad cars including a buffer block carried by one car, a chafing iron carried by an adjacent car provided with an inwardly extending tapering recess having a rounded end, a casting disposed between the block and iron, :1. tapering rounded neck extending laterally from the casting and pivoting against the rounded end of the recess, and means on the casting for guiding the casting when in engagement with the iron.

4. A buffer for railroad cars including a buffer block carried by one car having a convex bearing surface, a chafing iron carried by an adjacent car having a convex bearing surface symmetrical with respect to the bearing surface of the block, said iron further provided with a. recess, a casting having complemental concave bearing surfaces on the opposite sides thereof interposed between the block and iron for movable engagement with the convex bearing surfaces thereof, means formed integral with and extending laterally from one of the curved surfaces of the casting and freely carried and separable from said recess for supporting said casting, and means formed integral with the upper and lower surfaces of the casting and in engagement with the iron for guiding the casting during its movement.

A buffer for railroad cars including a buffer block having a convex bearing surface, a chafing iron carried by an adjacent car having a convex bearing surface symmetrical with respect to the bearing surface of the block, said iron further provided on the curved bearing surface thereof with a laterally disposed inwardly extending and rounded recess, a casting having complemental concave bearing surfaces on the opposite sides thereof, interposed between the block and iron for movable engagement with the convex bearing surfaces thereof, a tapering and rounded neck extending laterally from one of the curved surfaces of the casting and freely carried by and separable from said recesses for supporting said casting, and laterally extending flanges formed integral with the upper and lower surfaces of the casting and arranged in engagement with the upper and lower surfaces of the ironfor guiding the casting during its movement.

In testimony whereof I affix my signature in presence of two witnesses.
